/* Window that can serve as a target for 2D drawing.
|
|
*
|
|
* SFML::RenderWindow is the main class of the Graphics module.
|
|
*
|
|
* It defines an OS window that can be painted using the other classes of the graphics module.
|
|
*
|
|
* SFML::RenderWindow is derived from SFML::Window, thus it inherits all its features: mouse/keyboard/joystick input,
|
|
* events, window handling, OpenGL rendering, etc. See the documentation of SFML::Window for a more complete description
|
|
* of all these features and code samples.
|
|
*
|
|
* On top of that, SFML::RenderWindow adds more features related to 2D drawing with the graphics module (see its base
|
|
* class SFML::RenderTarget for more details). Here is a typical rendering / event loop with a SFML::RenderWindow:
|
|
*
|
|
* # Declare and create a new render-window
|
|
* window = SFML::RenderWindow.new( SFML::VideoMode.new( 800, 600 ), "SFML window" )
|
|
*
|
|
* # Limit the framerate to 60 frames per second (this step is optional)
|
|
* window.framerateLimit = 60
|
|
*
|
|
* # The main loop - ends as soon as the window is closed
|
|
* while window.open?
|
|
* # Event processing
|
|
* while event = window.getEvent
|
|
* # Request for closing the window
|
|
* if event.type == SFML::Event::Closed)
|
|
* window.close
|
|
* end
|
|
* end
|
|
*
|
|
* # Clear the whole window before rendering a new frame
|
|
* window.clear
|
|
*
|
|
* # Draw some sprites / shapes / texts
|
|
* window.draw( sprite ) # sprite is a SFML::Sprite
|
|
* window.draw( shape ) # shape is a SFML::Shape
|
|
* window.draw( text ) # text is a SFML::Text
|
|
*
|
|
* # End the current frame and display its contents on screen
|
|
* window.display
|
|
* end
|
|
*
|
|
* Like SFML::Window, SFML::RenderWindow is still able to render direct OpenGL stuff. It is even possible to mix
|
|
* together OpenGL calls and regular SFML drawing commands. When doing so, make sure that OpenGL states are not messed
|
|
* up by calling the saveGLStates / restoreGLStates functions.
|
|
*
|
|
* # Create the render window
|
|
* window = SFML::RenderWindow.new( SFML::VideoMode( 800, 600 ), "SFML OpenGL" )
|
|
*
|
|
* # Create a sprite and a text to display
|
|
* sprite = SFML::Sprite.new
|
|
* text = SFML::Sprite.new
|
|
* # ...
|
|
*
|
|
* # Perform OpenGL initializations
|
|
* glMatrixMode( GL_PROJECTION )
|
|
* # ...
|
|
*
|
|
* # Start the rendering loop
|
|
* while window.open?
|
|
* # Process events
|
|
* # ...
|
|
*
|
|
* # Draw a background sprite
|
|
* window.saveGLStates
|
|
* window.draw( sprite )
|
|
* window.restoreGLStates
|
|
*
|
|
* # Draw a 3D object using OpenGL
|
|
* glBegin( GL_QUADS )
|
|
* glVertex3f( ... )
|
|
* # ...
|
|
* glEnd()
|
|
*
|
|
* # Draw text on top of the 3D object
|
|
* window.saveGLStates
|
|
* window.draw( text )
|
|
* window.restoreGLStates
|
|
*
|
|
* # Finally, display the rendered frame on screen
|
|
* window.display
